Be it known that I, ARTHUR M. Laycocx, a subject of the King of Great Britain, and residing at Kingston, county of Luzerne, State of Pennsy vania, have invented certain new and useful Improvements in Boller-Bearings, of which the following is a specification.

The invention relates to rollerbearings. Its principal objects are to rovide a simple means whereby the bearing may be assembled and the rollers held in position against axial displacement. Other objects will appear as the description proceeds.

The bearing comprises inner and outer rings with interposed rollers; These rollers axial displacement by suitable means which includes a removable flange.

The various features of the invention will be understood from an ins ection of the accompanying drawing, in w ich, I

Figure 1 is an end elevation with parts cutaway to show the snap ring;

Fig.2 is a half sideelevation and half sectional view;

Fig. 3 is a detail showing a slight modification. v

The bearing comprises an inner ring 10 and an outer ring 12. As shown, the bearing is of the two-row type, although the invention is applicable to other types. The inner ring is rovided with a medially located outward extending radial flange 11, and the outer ring may be provided with an inwardly extending radial flange 13 at one end. The other end is counterbored as at 17 to provide a seat for an annulus 18. The seat 17 is located so that the annulus 18 will assume. a position symmetrical with the flange 13, and said annulus corresponds to flange 13, except that it is removable. outer periphery of the annulus or removable flange 18 is formed with a circumferentially extending groove 21 adapted to receive a split expansible snap ring 19. The

roove is of such a depth that the ring can e contracted and lie entirely in said roove,

no part extending beyond the sur ace of the flange.

The surface of the counter-bore is formed with groove 22, which registers with the groove in the annulus when the latter is in Application filed April 1a, 1916. 5.11am. 91,992.

position.

.less than the diameter of the stock of the snap ring.

The

The depth of the groove 22 is Preferabl the ring is made from round stock an the groove 22'is of a depth equal to the radius of the stock. I

Spaced around the circumference of the outer ring are a plurality of radial a ortures 23 opening into the groove 22 at t eir inner ends. In the drawings three of these apertures have been shown.

In assembling the bearing the row of rollers 16 is put in place between the rings in-the usual manner. The row of rollers 15, is then placed in position, the sna ring 19 pressed into the groove 21, and t e removable flange 18 is pushed into its po sition, when the snap ring will expand seating itself in the groove 22, but also forming a bead projecting into groove 21,

and thus locking the removable flange or annulus 18 in position to form an abutment for the ends of rollers 15 in the same manner as flange 13 forms an abutment for the ends of rollers 16.

The snap ring may be manipulated to contract it by inserting nails or pins through the apertures 23, and when so contracted t e annulus may be withdrawn.

In Fig. 3, a slight modification is shown. The removable flange 18 is made with a lip 24 which seats against the end of theouter ring 12. The cross sectional outline is the same in both forms.

Having thus described the invention, what is claimed and desired to be secured by Letters-Patent is:

1. In a roller bearing, an inner race ring an outer race ring, interposed rollers, one 0 said race rings at one end formed with an annular seat for a removable flange, a flange carried in said seat, said flange and seat formed with registering grooves, and a removable split ring arranged in said grooves to lock the flange and race ring together.

2. In a roller bearing, an inner race ring, an outer race ring, interposed rollers, one of said race rings at one end formed with an annular seat for a removable flange, aflange carried in said seat, said flange and seat formed with registering grooves, a removable split ring arranged in said grooves to lock the flange and race ring together, and

said bearing being formed to receive a tool formed with .gr00V08,'8.m1 a re to manipulate the split ring to push it out movable split ring arranged in said grooves 10 of locking sition. to lockthe flange and race ring together, 3. In a re er bearing, an innerrace ring, said latter race ring formed with a plurality 5-an outer race ring, interposed rollers, one of radial apertures extending through the of said race rings at one and formed with an rin and openin into the groove.
